Median household income in a particular county is $46,250. A researcher is interested to see whether students at the county community college have a median household income lower than the county overall. She selects 15 students at random and determines that 12 have a household income below the county median, one has an income equal to the county median, and two have a household income above the county median. She wishes to conduct her test using the 0.05 significance level. What is the decision rule?
